Variant Branching Pattern of the Right Internal Iliac Vessels in A Male - A Case Report

Abstract

Internal iliac vessels show frequent variations in their branching pattern. We saw variations in the branching pattern of right internal iliac vessels in a male cadaver. The internal iliac artery did not divide into anterior and posterior divisions. There were three common trunks: one for iliolumbar and lateral sacral arteries, another for inferior gluteal and internal pudendal arteries, and the third one for superior vesical and obturator arteries. The superior gluteal and middle rectal arteries arose directly from the main trunk of the internal iliac artery. The internal iliac vein did not have a main trunk. Its anterior and posterior divisions joined with the external iliac vein to form the common iliac vein. Knowledge of these variations might be useful for the urologists and surgeons.
